they dont, there is not a single of species of bear that have ever been known to hibernate. bears torper during winter, this is when they sleep, but can still wake up and walk around, hibernation is when an animal is in a deep sleep for the whole winter and cannot and will not wake up at all. torper is just like a lazy sunday morning when you wake up at 6:00, then fall asleep, then wake up and walk around again, then fall asleep. its the same concept
All kinds of bears technically don't hibernate. They enter into a phase called torpor which is like a deep slumber but they can awaken and often do from their slumber.Panda Bears, sun bears, and sloth bears do not hybernate.
It would go against all their survival instincts if they hibernated in the summer They give birth to their young during the hibernation period, in the winter . Being such a large mammal, they need time to nurture their young in relative protection from large males who have no qualms about eating a sows babies. Over the millennial of evolution they have become instinctual about hibernation. By the time the cubs are nine months or so, they have developed enough skills to survive with their mother's help. After they reach the age of two years they go off on their own
they start to go to sleep and when the spring come they began to wake up
True hibernators experience a marked drop in heart rateand body temperature and generally stay for a long period in a den. Polar bears instead enter a state ofwalking hibernation where their metabolism slows. Only pregnant polar bears enter a den, give birth, and emerge three months later.-They hunt along the Arctic shelfs looking for tasty seals, fish, and even humans.
Before the polar bear hibernates, it eats tons of food, which then supplements it through the winter. Naturally, While the polar bear is sleeping, it's heart rate slows also allowing the food to with stand such a long period of time.
some animals have to sleep the whole winter. That's why they eat so much in the winter so they can sleep through he whole winter and wake up in spring.
Ladybugs hibernate in the winter and wake up just as spring flowers are starting to bloom. This sleep period allows them to survive the cold weather, and you can mimic that winter rest period by placing them in the refrigerator.

when bears wake up they go around different fourum environments and look for food
They will most likely go back to sleep and be fine. It is difficult to wake a hibernating bat, as their heart rate has slowed. However, if they do wake up they can go back to sleep. If disturbed too much then they will burn calories, which are needed to survive the winter months, and die.
They sleep in at night and wake up in the morning.
